Median

In statistics and probability theory, a median is the number separating the higher half of a data sample, a population, or a probability distribution, from the lower half. The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one (e.g., the median of {3, 3, 5, 9, 11} is 5). If there is an even number of observations, then there is no single middle value; the median is then usually defined to be the mean of the two middle values
(the median of {3, 5, 7, 9} is (5 + 7) / 2 = 6), which corresponds to interpreting the median as the fully trimmedmid-range. The median is of central importance in robust statistics, as it is the most resistant statistic, having a breakdown point of 50%: so long as no more than half the data are contaminated, the median will not give an arbitrarily large result.
A median is only defined on ordered one-dimensional data, and is independent of any distance metric. A geometric median, on the other hand, is defined in any number of dimensions.

Statistics

Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. In applying statistics to, e.g., a scientific, industrial, or societal problem, it is conventional to begin with a statistical population or a statistical model process to be studied. Populations can be diverse topics such as "all persons living in a country" or "every atom composing a crystal". Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments.

When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey samples. Representative sampling assures that inferences and conclusions can safely extend from the sample to the population as a whole. An experimental study involves taking measurements of the system under study, manipulating the system, and then taking additional measurements using the same procedure to determine if the manipulation has modified the values of the measurements. In contrast, an observational study does not involve experimental manipulation.

In 2003, following the temporary caesura of Desaparecidos, Dalley formed Statistics, an electronic-tinged solo project, and signed onto the Jade Tree Records label. After releasing a self-titled extended play in 2003 and two studio albums titled Leave Your Name and Often Lie in 2004 and 2005, respectively, Dalley chose to focus on other projects, effectively putting Statistics on hiatus. However, in 2013, eight years after Often Lie, Dalley released a new studio album titled Peninsula on Afternoon Records, featuring a collaboration with Minnesota-based singer-songwriter Sean Tillman (a.k.a. Har Mar Superstar). Dalley hopes to create visuals in the form of music videos for songs in Peninsula, something that he has never done in his prior musical ventures.

Regional terminology

There is no international English standard for the term. Median, median strip, and median divider island are common in North American and AntipodeanEnglish. Variants in North American English include regional terms such as neutral ground in New Orleans usage.

In British Englishcentral reservation is the preferred usage; it also occurs widely in formal documents in some non-British regions such as South Africa, where there are other informal regional words, for example middelmannetjie, which originally referred to the hump between wheel ruts on a dust road. Among other coinages, central nature strip occurs in Australian English.

Median (geometry)

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposing side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.

Relation to center of mass

Each median of a triangle passes through the triangle's centroid, which is the center of mass of an infinitely thin object of uniform density coinciding with the triangle. Thus the object would balance on the intersection point of the medians. The centroid is twice as close along any median to the side that the median intersects as it is to the vertex it emanates from.

Equal-area division

Each median divides the area of the triangle in half; hence the name, and hence a triangular object of uniform density would balance on any median. (Any other lines which divide the area of the triangle into two equal parts do not pass through the centroid.) The three medians divide the triangle into six smaller triangles of equal area.
